Yes, that's also a good one. I loved how creative she was with her telepathy back then before it only become about creating psychic knives.
Another favorite issue of mine is UXM Annual 11 when Claremont established Betsy as having an indomitable will akin to Wolverine and Storm. The three strongest characters of the team in terms of willpower and fighting spirit. I guess that could explain the reference to her being "Diet Storm."
